A simple authentication provider that supports SASL authentication using the PLAIN mechanism for
version 3 (or above) of the CQL native protocol.
To activate this provider, add an advanced.auth-provider
section in the driver configuration, for example:
datastax-java-driver {
advanced.auth-provider {
class = com.datastax.driver.api.core.auth.PlainTextAuthProvider
username = cassandra
password = cassandra
// If connecting to Datastax Enterprise, this additional option allows proxy authentication
// (login as another user or role)
authorization-id = userOrRole
}
}
See reference.conf
(in the manual or core driver JAR) for more details. /**
